Update OCaml findlib to 1.2.6

Changes:

-  1.2.5: Fix: Again CR deletion... Turns out some OS do not  understand '\r'
   but only '\015' (thanks to Isaiah Weiner)
   Support for Win64 (untested; thanks to David Allsopp)
   ocamlfind no longer emits auto-generated -ccopt options. These  tend to
   accumulate, and it is possible that for large projects  the maximum command
   line length is exceeded. Current versions of  the O'Caml compilers do not
   need these extra -ccopt anyway, so  this code is completely dropped.

-  1.2.4: Fix: Bigarray needs unix (Thanks to Markus Mottl)
   Fix: In the version of camlp4 provided by O'Caml 3.11 various  libraries do
   not contain dynlink anymore. Because of this, dynlink  becomes a
   prerequisite of camlp4. (Thanks to Martin Jambon)
   Attempt: Fixing the space issue for paths (Win32). It is unclear  whether it
   is solved. (Thanks to Christophe Troestler)

-  1.2.3: Solving the CR deletion differently, to  make OS X happy.

-  1.2.2: Fix: Problem with CR character (Cygwin)  (Thanks to David Allsopp)
   Fix: Case-insensitive filesystems (partially solved)  (Thanks to David
   Allsopp)
   Fix: File name with backslashes at the end (Win32; thanks to Dmitry
   Grebeniuk)

-  1.2.1: Fix: Camlp4 rules now activate the stream parser extension

-  1.2: Fix in build scripts: Prepending $(prefix) when installing safe_camlp4
   (thanks to Daniel Janus)
   Non-existing -I directories are ignored (thanks to Nicolas Pouillard)
   A script to create a MacOS X package (thanks to Pietro Abate)
   Better support for Windows (with help from Robert Roessler and David
   Allsopp)
   Support for camlp4 on O'Caml 3.10
   Fix: "ocamlfind install" with "-patch" option writes now correct META file
   for the case that subpackages occur
   Adding environment variable OCAMLFIND_IGNORE_DUPS_IN to reduce the number of
   warnings ocamlfind emits
